What are some of the key metaphors used in Chapter 47 to describe the greatness of Sai Baba and the value of his stories?

Chapter 47 employs several powerful metaphors to illustrate the supreme nature of Sai Baba and his teachings. His grace is likened to the "sun of His grace," in whose light the "firefly of worldly existence hides." His stories are described as an "ocean," and listening to them is like sitting under the shade of a "Kalpataru (wish-fulfilling tree)," where desires are fulfilled instantly. The chapter also poses rhetorical questions to emphasize this abundance: "In the house of the Sun, who worries about a lamp?" and for one who drinks the "nectar" of his stories, poison has no effect. Even the holy River Ganges is personified as desiring the "dust from the feet of saints" like Sai to purify herself, showcasing his immense spiritual stature.
